Dusty is about 5 yrs. old and we've had her for 3 years. She was a stray that decided to live on our patio, but she is now an indoor/outdoor (only during the day) cat. She is so affectionate, and really is the perfect pet in every way, BUT she will not play. We've tried every toy known to attract cats, including dangling a string. We have balls, toy mice, feather toys, laser lights, you name it and we've tried it. She is just not interested. What's up with that? I thought all cats liked toys?
